Hydroxysafflor Yellow A (HSYA) Protects Endplate Chondrocytes Against IL-1β-Induced Injury Through Promoting Autophagy

Figure 1

HSYA reverses IL-1β-induced growth inhibition of endplate chondrocytes. (a) The chondrocytes were identified using toluidine blue staining. (b) The expression of collagen II was detected by immunofluorescence staining. (c) Endplate chondrocytes were treated with different concentrations (0, 5, 10, 25, 50, or 100 μM) of HSYA. The viability of endplate chondrocytes was detected using CCK-8. (d) Endplate chondrocytes were treated with IL-1β, IL-1β + 10 μM HSYA, or IL-1β + 25 μM HSYA. The viability of endplate chondrocytes was detected using CCK-8. (e) The proliferation of endplate chondrocytes was detected using EdU staining. , ∗∗ compared with the control group. , compared with IL-1β.
